This year, whenever you sign and date a legal document, whether it be a tenancy contract, an inventory, an updated will or anything else, always put the year as 2020.
If you just put, for example 01/02/20 (for 1st of February this year), sooner or later someone, somewhere is going to change it to 01/02/2019 and then claim it was actually signed a year of more earlier to their benefit and your dismay - so 2020 everytime!
(And this is also the year you have 20:20 vision - so all those missed broken drawers or stains on curtains on checkout inspections will be a thing of the past - this year, all year, you have 2020 vision and will miss nothing! So make the most of it).
